CHAPL'ET.

- To all whom it may concern:

Be it known that I, GEORGE L. VVArrr, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Chaplets, of which the 'following is a specification.

This invention relates to a chaplet for use in holding parts of a mold in place during the operation of casting articles in the mold cavity.

- It is the object of this invention to produce chaplets of this character expeditiously and economically and to so construct the same that they provide a maximum amount of strength for the weight of metal in the same and that when in use the same eflect'ually and reliably hold the parts of the mold in the proper relative position during the operation of pouring the metal into the N cavity of the mold.

In the accompanying drawings: Figure 1 is a vertical section of a mold or flask adapted for casting car wheels and provided with chaplet-s embodying my improvements. Fig. 2 is a perspective View of one form of chaplet constructed in accordance with my invention. Fig. 3 is a top plan view of the same. Fig. 4c is a plan view of a blank from which the chaplet shown in Figs. 2 and 3 is constructed. Fig. 5 is a perspective View showing a form of Chaplet embodying my invention butconstructed slightly different from that shown in Figs. 2 and 3. Fig. 6 is a top plan View showing another modification of a chaplet embodying my improvements. Fig. 7 is a perspec-' tive view of another form of chaplet em bodying my invention.

Similar characters of reference indicate corresponding parts throughout the several views.

Although this chaplet is capable of use in various kinds of molds or molding flasks I have shown the same in Fig. 1 in connection with a flask or mold which is designed for casting car wheels and which comprises a bottom board 1, a nowel or drag 2 resting on the bottom board and containing thelower part 3 of the molding sand, acope 4' Specification of Letters Patent.

nowel, and a center or hub core 9 which is supported at its upper and lower ends by' suitable prints on the sand of the cope and nowel. In its complete form a mold cavity 10 is formed between these mold sections in which a car wheel is cast, the metal for this purpose being poured into the mold cavity through the sprues 11 in the central part of the sand in the cope.

On its underside and above the pan core the cope is provided with a plurality of vertical sockets 12 extending upwardly from the under side of the cope. and 3, 13 represents my improved chaplet as a whole. Each of these chap-lets is pro: vided with a horizontal flat base 14 which is adapted to rest on the upper side of the pan core, and a shahk or standard 15 pro jecting upwardly from the base and adapted to engage one of the sockets 12 of the cope for the purpose of preventing the pan core from rising or floating as the metal is poured into the mold cavity.

The shank of the chaplet shown in Figs. 1, 2- and 3 comprises an outer=upright part or flange 16 which extends upwardlyfrom the edge of the base and an inner part or flange 17 arranged over the top of the base and at right angles to the first mentioned flange. A shank of L-shaped cross section is by this means formed. The upper parts of the edges of these flanges are inclined, as shown at 18 in Fig. 2, which edges converge upwardly so that as a whole the shank tapers upwardly whereby the same may be engaged with the socket 12 of the cope with a wedging or friction fit for reliably holding the chaplet in place. The lower ends of the inclined edges of the shank flanges terminate in horizontal upwardly facing shoulders 19 which are arranged about midway of the height of the shank and which are adapted to engage with the lower side of the cope and thus serve as stops which limit the extent which the shanks of the Chaplets may be pushed upwardly in the socket of the cope. A chaplet of this character is preferably constructed of a flat notched or cut away so as to form the inclines and shoulders 18, 19 of the chaplet.

This blank is folded along a line21 extend ing transversely from the inner end of the slit 20' to the opposite longitudinal edge of the blank so as to bring the two parts of the same constituting the base 14 and the shank 15 at right angles to each other. That part of the blank formingthe shank is then bent along a'line 22 arranged'lengthwise between the longitudinal edges of the blank and extending from the inner end of the slit 20. to the upper end of the tapering part of the shank whereby the shank is completed by forming two flanges or parts, one of which, the outer, is formed integrally with the base and extends upwardly therefrom at one of its longitudinal edges and adjacent to one of its transverse edges while the other or inner flange projects inwardly from the outerflange over'the central part of the base but is disconnected from the A chaplet constructed in this manner is not onl very strong and durable and. capable of resisting the roughest usage or the greatest weight which. is liable to be imposed upon the same but the same can also be produced expeditiously and economically from sheet metal with comparatively little waste of material. 7

If desired the shoulders may be omitted from both edges of the shank flanges in which case these edges of the shank 15 may be inclined continuously from the lower end to the upper end of the'shank and produce a continuous taper upwardly from the base 14:, as shown in Fig. 7. Instead of providing both flanges of the shank with an inclined edge and an upwardly facing shoulder only one of the flanges for instance the inner one 23 may be provided with such an incline 24: and'shoulder 25 while the outer flange 26 may be provided with an incline 27 extending from the base 14 to the upper end of the shank 15 as shown in Fig. 5.

In the construction of chaplet shown in Figs. 2, 3 and 5, the flanges of the shank or standard are arranged at right angles to each other but desired the shank or standard may be constructed so as to curve continuously from one of its upright edges to the other over the base 14 as shown at as, in Fig. 6.

I claim as my. invention:

1. A chaplet comprising a base, and a shank rising from said base and having a part extending upwardly from the edge of the base and another part projecting over the top of the base, said shank tapering upwardly.

QLA chaplet comprising a base, and a shank rising from said base and having a part extending upwardly from the edge of the base and another part projecting over the top of the base, said shank being provided with an upwardly facing shoulder.

3. A chaplet comprising a base, ?-and a shank rising from said base and having a part extending upwardly from the edge of the base and another part projecting'over the 'top of the base, said shank tapering upwardly and provided with an upwardly fac ing shoulder.

WVitness my hand this 29th day of July.
